I have 2 Hard drives installed in my computer. On one hard drive, I had Ubuntu 14.04 and the other was a Windows 7 HDD. Today I had to delete the Ubuntu HDD. I did this from my Win7 Partition manager.

Now when I try to boot my computer from the Live usb, it sends me int GRUB Rescue mode. If I try to load my Win7 HDD, it sends me to GRUB Rescue mode. No matter where I set my boot device/partition, I land in GRUB Rescue.

How can I get my Live USB to start, so that I can install GRUB and Ubuntu? Please go easy on me, I am very much still a noob when it comes to the world of Linux. I've only been dabbling for about 10 months now. Any help is very much appreciated. Thank you.

Have you tried opening up the BIOS and changing the boot order so your USB will boot before Windows Boot Manager? If not, hold down DEL, or either one of the Function keys. (Usually F8 or F12) To access the BIOS. Go to the Boot tab and change the order, then save configuration and exit. (If this doesn't work, you might want to try changing UEFI boot mode to Legacy, if available) If you've already tried this, however, then I can't be of much help. Hope you get it working! –  user294326 Jun 17 '14 at 12:01
